Political stunt: Alex Salmond waved the Scottish flag behind David Cameron as Murray won the Wimbeldon title. An act that angered many

Scottish tennis ace Andy Murray said he does not know which nation he will play for if Scotland becomes independent.

Murray said he "didn't like it" when First Minister Alex Salmond unfurled the Scottish flag behind Prime Minister David Cameron in the Royal Box at his historic Wimbledon victory, in an interview with the Sunday Times.

When asked who he would play for if Scotland left the UK, he said: "I don't even know."

He said Mr Salmond "seemed perfectly nice" when the pair met, but added: "I didn't like it when he got the Scottish flag up at Wimbledon."

"I started competing for Great Britain when I was 11. A lot of people forget that."

He would not be concerned if he has children and they do not have Scottish accents, he added.

"I wouldn't have thought that would be high on my list of priorities," he said.

Murray provoked a backlash in 2006 when he joked he would support "anyone but England" in the football World Cup, a comment he said that he later regretted.

A spokesman for Mr Salmond said: "Andy is reigning Wimbledon Champion and a great Scottish tennis player. He has made it clear a number of times that he doesn't want to comment on Scottish politics.

"Everyone should just accept that and let him get on with playing tennis, rather than attempt to put him on the spot about who he would play for in a future Olympics."

Patricia Ferguson, Scottish Labour's sport spokeswoman, said: "Alex Salmond's antics embarrassed Scotland and it appears he embarrassed Andy Murray as well. While all eyes were on Andy at his moment of triumph and one of the greatest moments in Scotland's sporting history, the First Minister's desperate attempts to steal the limelight made him look very foolish.

"With the Commonwealth Games just a few weeks away, and the eyes of the world on Glasgow, let's hope Alex Salmond sees sense and leaves his Saltire at home."
